Does anyone on this Forum have any experience with Audio research ref 610t monoblocks


Good afternoon. 
I have a chance to pick up a set of very nice Audio research ref 610t monoblocks . I believe there rated at 600 wpc, class A, or A/B, not sure. I think they use around 16-20 tubes. It’s a older amp, older technology. But in the 70s they sold for around 40k for the set. Anyways, I wanted to know if anyone here on the board has a pair, has heard them, and get your honest opinion. How do they sound? Are they noisy? 
How would you compare them say to a Prima Luna,, etc, etc. I know they are super heavy, I think 170 pounds each . And the tubes can be expensive. But I’m trying to find some people that can tell me there experience with these amps. Thank you

Lalitk, 

I don’t have one specific system as some. I have a pair of Magico s3 mk2 speakers , boulder Hercules amp, a couple of dedicated dacs, Also a pair of La scala speakers that I already have a Prima Luna amp and Preamp, as well as a pair of Atc 50s. I wasn’t aware that we are only allowed to have one system to be able to discuss audio equipment. My bad. Before I buy or add something to my collection of gear I’d like to ask around . Thank you for your input , much appreciated. I just acquired a Benchmark La4 after all the good feedback for a neutral preamp. Thank all for your recommendations.
